BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording medium mounting apparatus in which a recording medium such as a removable hard disk is loaded, and more particularly, to a recording medium mounting apparatus having an autoloading mechanism.

In recent years, the rapidly spreading network of broadband, low-cost high-performance PCs, penetration of digital still cameras and digital video cameras, and digital broadcasting are in progress. Digitalization of information is in progress. In addition, in terms of information handling equipment such as a PC capable of recording television and a television and a telephone that can be connected to the Internet, the company is entering a new stage beyond conventional categories such as information equipment and home appliances.

Currently, in the field of AV equipment and the like, a 3.5-inch type fixed hard disk drive is used as a recording medium for recording a large amount of information. However, the fixed hard disk drive as described above cannot cope with the rapidly increasing capacity every year.

On the other hand, recent high-density technology has developed a 2.5-inch or 1.8-inch removable hard disk drive capable of sufficiently storing large amounts of data.

In such a removable hard disk, a drive mechanism for rotating the disk, a magnetic head for recording and reproducing, and the like are built in the removable hard disk. Therefore, in general, only a connector is used to exchange signals and the like between the removable hard disk and an external device (recording medium mounting apparatus) on which the removable hard disk is loaded.

Therefore, when the removable hard disk is mounted on the recording medium mounting apparatus, the removable hard disk side connector needs to be mounted on the recording medium mounting apparatus side connector, and when the removable hard disk is removed, the recording medium is mounted. It is necessary to detach the removable hard disk side connector from the device side connector, and this technique is described in the following patent document 1 etc., for example.

(Patent Document 1) JP 4-47554 A

However, in the patent document 1, when attaching a recording medium-side connector such as a removable hard disk to the recording medium-mounting device-side connector, the user must perform it manually. There is a problem.

Moreover, since it is inserted manually, it is not easy to store all of the recording medium in the apparatus, and it is easy to have a structure in which a part thereof protrudes out of the apparatus. For this reason, when an external force acts on a part of the recording medium during operation, there is a problem such as data error or data destruction.

When the recording medium is loaded in an abnormal direction, it is also necessary to prevent the recording medium from being conveyed into the apparatus.

In addition, when considering a loading mechanism for automatically conveying the recording medium, it is necessary to consider the simplification and miniaturization of the configuration, and to ensure the connection between the recording medium and the connector.

An object of the present invention is to provide a recording medium mounting apparatus having an autoloading mechanism capable of automatically conveying a recording medium having a connector.

In the present invention, since the recording medium can be automatically conveyed only by loading the recording medium into the insertion portion of the apparatus, the ease of use is improved and the burden on the user can be reduced. In addition, since the entire conveyed recording medium can be stored inside the apparatus, no external force acts on a part of the recording medium during operation, thereby preventing occurrence of data error or data destruction during recording or reproduction.

In the above description, the retracting member has a locking portion for hanging a recess formed on a side surface of the recording medium, and the locking portion is supported to be able to swing upward and downward with respect to the movable member, and the locking portion enters the recess from above. In this case, a configuration in which the recording medium is caught is preferable.

In the above means, it is possible to hang the concave portion from the height direction of the recording medium, so that the recording medium mounting apparatus can be provided with a small horizontal dimension.

More specifically, the movable member is provided with a pressurized portion pressurized by the recording medium, and on the side portion in the width direction perpendicular to the insertion direction, a guide long hole for guiding the movement of the engaging portion of the pulling member, And a guide member having a support hole for setting the locking portion to a non-locking state separated from the recess, and an inclined portion for guiding the locking portion from the support hole into the guide long hole to guide the locking portion to the locking state. ,

In the vicinity of the opening hole 51 of the movable member 50, guide pins 54, 55 protruding upward and downward from the base 50A are formed. In addition, the function of the said guide pins 54 and 55 is mentioned later.

The windows 56 and 56 are formed in the side parts 50B and 50B of the said moving member 50, and the pulling-out members 70 and 70 are formed in the vicinity of these windows 56 and 56. As shown in FIG. The drawing member 70 is made of synthetic resin or the like, and rotation is freely supported on the shaft 71 formed at the Y1 side position of the side portion 50B.

The drawing member 70 has an arm portion 72 extending in the Y2 direction and a latching piece 73 extending in the Z1 direction. A locking portion 74 protruding inwardly is formed on the inner surface of the tip of the arm portion 72. In addition, a restricting protrusion 75 protruding outward is formed on the outer surface of the arm portion 72 and is inserted into the window 56. Accordingly, the pulling member 70 is freely supported in the vertical direction about the shaft 71 within the range in which the regulating projection 75 abuts on the upper and lower edge portions of the window 56. At the front end of the Y2 direction of the side parts 50B and 50B of the said moving member 50, the engaging pieces 57 and 57 extended in the Z1 direction of illustration are integrally formed. The hanging pieces 57, 57 are slightly bent inwardly, and an elastic member S1 made of a coil spring or the like between the hanging pieces 57, 57 and the hanging pieces 73, 73 of the drawing member 70. , S1) is hypothesized in a compressed state. Therefore, the retracting member 70 is elastically supported in the direction in which the distal end of the arm portion 72 is rotated downward (Z2 direction).

The movable member 60 is formed of a metal plate, and an opening 61 is formed in the central portion of the movable member 60 so as to have an approximately center hole. The 2nd rack part 62 is formed in the edge part of the opening part 61 by the side of illustration X2.

The dimension of the width direction (X direction) of the said movable member 60 is formed in the dimension similar to the width dimension of the narrow part of the base 50A of the said movable member 50, and the said movable member 60 Is in contact with the lower surface (surface on the Z2 side) of the base 50A. Guide long holes 63 and 64 are formed at both sides of the opening 61 of the movable member 60, and the guide long holes 63 and 64 are formed in the guide long holes 63 and 64.

At the edge portion of the movable member 60 at the side of the drawing Y1 and on the side of the X2 side, a hanging portion 65 protruding in the direction of the drawing X2 is formed. An elastic member S2 made of a coil spring or the like is provided between the engaging portion 65 and the engaging portion 58 formed on the side surface of the base 50A of the movable member 50. Therefore, the movable member 60 and the movable member 50 are pulled in the Y direction from each other in the overlapped state. Therefore, the lower ends of the guide pins 54, 55 formed on the movable member 50 are generally in contact with the Y1 side ends of the guide long holes 63, 64 of the movable member 60.

As shown in FIG. 2, in the area | region between the said one guide member 30 and the other guide member 30 on the surface of the said base chassis 20, the slide member 80 which consists of a metal plate formed in rectangular shape. Is formed. A shaft 81 is formed at the center of the slide member 80, and its tip extends from the lower surface of the slide member 80 in the direction Z2 shown. The power transmission means 90 is freely rotated at the tip of the shaft 81. The power transmission means 90 is constituted by a two-stage gear in which a small diameter pinion gear 92 is constantly formed on an upper portion of the large diameter pinion gear 91, and a lower surface of the large diameter pinion gear 91 is illustrated in Z2. The sliding pin 93 which protrudes in the direction is formed. Moreover, when the number of teeth of the said large diameter pinion gear 91 is N1, and the number of teeth of the small diameter pinion gear 92 is N2, it is N1> N2.

Two guide long holes 82, 83 extending in the Y direction are formed at both edge portions in the width direction of the slide member 80, and the movable member 50 is formed in the guide long holes 82, 83. The tip ends of the guide pins 54 and 55 formed in the " That is, the guide pins 54, 55 are inserted through the guide long holes 23a, 23b of the base chassis 20, and the front ends thereof are the guide long holes 82, 83 of the slide member 80 again. It is inserted in. Therefore, the slide member 80 is in the state which can be moved to the Y direction by the said guide pin 54, 55 and the guide long hole 82, 83. FIG. In addition, the slide member 80 is movable in the Y direction on the surface of the base chassis 20, and moves in the gap between the base chassis 20 and the substrate 39 when moving in the Y1 direction.

In the vicinity of the guide long hole 83, a protruding piece 84 that protrudes in a substantially triangular shape from the edge of the slide member 80 in the direction of drawing X1 and is bent in the direction of drawing Z2 is formed. The protruding piece 84 is inserted into the long hole 24 formed in the base chassis 20, and the front end thereof reaches the lower surface of the base chassis 20. A catching portion 85 is formed at the tip of the protruding piece 84, and an elastic portion formed of a coil spring or the like between the catching portion 85 and the catching portion 26 formed at the front position of the base chassis 20. The member S3 is hypothesized in a compressed state. Therefore, the slide member 80 is always elastically supported forward (on the Y2 direction) on the base chassis 20.

In the state where the slide member 80 is mounted on the surface of the base chassis 20, the small-diameter pinion gear 92 of the power transmission means 90 has an opening 21 of the base chassis 20. It meshes with the 1st rack part 21a formed in the side. In addition, the large-diameter pinion gear 91 of the power transmission means 90 is inserted into the opening hole 51 of the movable member 50 and the opening 61 of the movable member 60, and the movable member ( Meshes with the second rack portion 62 formed in the second column; That is, the said power transmission means 90 is meshed by the 1st rack part 21a and the 2nd rack part 62 on both sides of a X direction.

The sliding pin 93 formed in the power transmission means 90 is inserted into the first sliding groove 12a formed on the surface of the cam member 12, and in the first sliding groove 12a. It is possible to move freely.

The operation of the recording medium mounting apparatus 10 will be described below.

(Initial state)

5 and 6 show an initial state before the hard disk is inserted, FIG. 5 is a plan view of the recording medium mounting apparatus, and FIG. 6 is an enlarged side view showing the front portion of the recording medium mounting apparatus.

As shown in FIG. 5, the cartridge 2 of the recording medium 1 of the recording medium mounting apparatus 10 surrounded by the inclined surfaces 31a, 32a, 33a formed on the pair of guide members 30, 30. In the initial state before the insertion portion 10A is inserted, the cam member 12 is rotated in the clockwise rotation direction in FIG. 3. For this reason, the sliding pin 93 of the said power transmission means 90 is separated from the Y2 side (axis 11a) in the said wide part 12a3 of the 1st sliding groove 12a formed in the said cam member 12. Side).

At this time, the movable member 50 and the movable member 60 are moved to the front position in the Y2 direction in a substantially integrated state by the elastic support force of the elastic member S2. Similarly, the slide member 80 is also moved to the front position by the elastic support force of the elastic member S3.

As shown in FIG. 6, in the initial state, as a result of the movement of the movable member 50 to the front position, the arm portion 72 of the pulling member 70 resists the elastic bearing force of the elastic member S1. Is rotated in the counterclockwise direction. That is, the locking part 74 of the drawing member 70 is supported by the support part 32f in the support hole 32e raised to the inclined part 32d of the guide member 30. As shown in FIG.

Moreover, the actuator 17a1 of the 1st switch member 17a is pressurized by the press part 53 of the moving member 50, and the switch state of the said 1st switch member 17a is set to OFF. As shown in FIG. 5, the rocking member 15 is rocked in the counterclockwise rotation direction, the actuator 17b1 of the second switch member 17b is pressed by the pressing section 15b, and the second switch member. 17b is set to ON, and the 3rd switch member 17c is set to OFF.

As shown in FIG. 5, the rocking member 15 is rocked in the counterclockwise rotation direction, and the actuator 17b1 of the second switch member 17b is pressed by the pressurizing portion 15b, so that the second switch member 17b is set to ON, and the 3rd switch member 17c is set to OFF. Therefore, the control part can detect from the rotation amount of the cam member that the moving member 50 is located at the insertion standby position.

(Insertion action)

In this initial state, the cartridge 2 of the recording medium 1 is inserted into the inserting portion 10A. When the cartridge 2 is inserted into the inserting portion 10A, each bottom surface 31 of the guide member 30, 30, on which both side surfaces 2B, 2B of the cartridge 2 are formed at both ends in the X direction, It is guided in the insertion direction (Y1 direction) in the state sandwiched between the side surface 32 and the upper surface 33.

When the cartridge 2 is inserted in the inserting direction, the front surface 2A of the cartridge 2 abuts against the pressurized portions 52a and 52a formed on the movable member 50, and the movable member 50 is Resistant to the elastic support force of the elastic member S3, the cartridge 2 is moved in the insertion direction simultaneously with the cartridge 2. At the time of insertion of the cartridge 2, the elastic member S3 functions as a damper of the movable member 50, whereby the insertion feel can be enhanced.

Here, when the movable member 50 is moved in the inserting direction, the lower ends of the guide pins 54, 55 of the movable member 50 are the Y1 side of the guide long holes 63, 64 of the movable member 60. Since the end portion is pressed in the insertion direction, the movable member 50 and the movable part material 60 are moved in the insertion direction in an integrated state. At this time, the power transmission means 90 having a large diameter pinion gear 91 meshing with the second rack portion 62 of the movable member 60 is also moved in the insertion direction, and the power transmission means 90 Since the sliding pin 93 is located in the wide portion 12a3 of the cam member 12, it is possible to move in the insertion direction in the wide portion 12a3 (see Fig. 7). Therefore, it is possible to avoid that the damper function by the elastic member S3 is prevented by the power transmission means 90.

As shown in FIG. 7, when the moving member 50 is moved in the insertion direction, the pulling member 70 is also moved in the insertion direction together with the moving member 50. Then, when the locking portion 74 of the pulling member 70 moves from the supporting portion 32f of the guide member 30 to reach the inclined portion 32d, the pulling member 70 causes the elastic member S1. Since the elastic member is elastically supported in the illustrated clockwise rotation direction, the locking portion 74 can lower the inclined portion 32d. However, in the initial stage of insertion, since the locking portion 74 is supported by the stepped portion 2c formed on the side surface 2B of the cartridge 2, the rotation of the inlet member 70 is restricted so that the locking portion The 74 is restricted from reaching the guide long hole 32c. Then, when the cartridge 2 is inserted and the recessed portion 2d formed on the side surface 2B reaches a position overlapping the inclined portion 32d of the guide member 30, the drawing member 70 rotates. Is permitted, the locking portion 74 descends the stepped portion 2c to reach the guide long hole 32c and at the same time hangs the recessed portion 2d.

Thus, in this invention, since the recessed part 2d of the cartridge 2 can be hooked | hung by lowering in the height direction (Y direction), compared with the case where the cartridge 2 is hung from a lateral direction. Therefore, the width dimension of the whole recording medium mounting apparatus 10 can be made small. Therefore, in particular, the width direction of the recording medium mounting apparatus 10 can be reduced in size.

At this time, since the pressurizing portion 53 formed on the movable member 50 is out of the actuator 17a1 of the first switch member 17a, the switch state of the first switch member 17a is turned off. It turns ON. Therefore, the control part at the apparatus main body side can detect that the cartridge 2 is inserted into the insertion portion 10A of the recording medium mounting apparatus 10.

When the cartridge 2 is incorrectly inserted into the inserting portion 10A in an abnormal state, for example, when the rear side 2D side of the cartridge 2 is inserted toward the inserting portion 10A, or the cartridge ( When it is inserted in the upside down state of 2), the locking portions 74 and 74 of the pulling member 70 cannot hang the recesses 2d and 2d of the cartridge 2. For this reason, the rotation of the drawing member 70 is not allowed, and the drawing member 70 is maintained in the state shown in FIG.

In addition, when the cartridge 2 in an abnormal direction is pushed in the insertion direction, the drawing member 70 is moved slightly in the insertion direction in the state shown in Fig. 6, but the catching portion 74 is moved to the support hole ( In contact with the restricting portion 32g of 32e), the pulling member 70 can no longer be moved in the insertion direction. As a result, the pressing section 53 can maintain the pressed state of the actuator 17a1 of the first switch member 17a and can prevent the switching of the switch state of the first switch member 17a. Therefore, it becomes possible to prevent the cartridge 2 in the abnormal direction from being automatically conveyed in the insertion direction by the loading operation as described later. That is, it is possible to prevent the cartridge 2 in an abnormal direction from being conveyed into the apparatus.

(Loading operation of cartridge)

When the control unit detects that the cartridge 2 is inserted in a normal state and the first switch member 17a is switched to the ON state, the control unit starts the drive motor M to counterclock the cam member 12. Rotate in the direction of rotation.

When the cam member 12 is rotated in the counterclockwise rotation direction, the sliding pin 93 formed in the power transmission means 90 is moved in the insertion direction along the first sliding groove 12a. At this time, since the small-diameter pinion gear 92 is engaged with the first rack portion 21a and rotates clockwise, the power transmission means 90 is moved in the insertion direction. The slide member 80 on which the power transmission means 90 is mounted is moved in the insertion direction while resisting the elastic member S3.

At the same time, since the second rack portion 62 engaged with the large-diameter pinion gear 91 is sent in the insertion direction by the clockwise rotation of the power transmission means 90, the second rack portion ( The movable member 60 having the 62 is moved in the insertion direction. When the movable member 60 is moved in the insertion direction, since the movable member 50 is pulled in the insertion direction through the elastic member S2, the movable member 50 is also inserted together with the movable member 60. Is moved in the direction. Then, when the moving member 50 is moved in the insertion direction, the cartridge 2 that is caught by the locking portion 74 of the pulling member 70 mounted on the moving member 50 automatically records the recording medium. It is conveyed inside the mounting apparatus 10. That is, the cam member 12, the power transmission means 90, the moving member 50, the drawing member 70, and the like constitute a loading mechanism for conveying the cartridge 2 in the insertion direction.

The cartridge 2 is inserted in a state in which both side surfaces 2B and 2B are held on three surfaces of the bottom surface 31, the side surface 32, and the top surface 33 of the guide member 30, 30. , But when the cartridge 2 reaches the inner side of the guide member 30, 30, the guide member 30, 30 in the guide grooves 2b, 2b formed in the both side surfaces 2B, 2B. Since the guide protrusions 32h and 32h formed on the inner wall of the are inserted, it is possible to move the cartridge 2 in the insertion direction in a more stable posture.

As shown in FIG. 8, when the cartridge 2 is loaded, the control pin 15a of the swinging member 15 has the outer peripheral end (in the second sliding groove 12b of the cam member 12). It is located in parts other than 12b1) and the inner peripheral part 12b2, and the oscillation member 15 is set to the neutral position. Therefore, since the second switch member 17b and the third switch member 17c are both in the unoperated state, the controller can grasp that the cam member 12 is in the loading state.

(Connector operation)

As shown in FIG. 8, when the sliding pin 93 passes through the connection part 12a4 of the 1st sliding groove 12a, the said sliding pin 93 is moved to the insertion direction by the small arc groove 12a2. As shown in FIG. 9, when the sliding pin 93 reaches the innermost periphery 12a5 of the 1st sliding groove 12a, the said cartridge which hangs on the pulling-in member 70 according to the movement of the sliding pin 93 ( The connecting portion 42 of the internal connector 40 is inserted into the opening 2a formed in the front surface 2A of 2).

When the fitting connector 3 of the cartridge 2 and the opening portion 43 of the internal connector 40 are attached to each other, an insertion load due to frictional resistance or the like occurs between them. For this reason, even if the movable member 60 which engages with the large diameter pinion gear 91 of the said power transmission means 90 moves to an insertion direction, the movable member provided with the pulling-in member 70 which hangs the said cartridge 2 is carried out. 50 cannot move together with the movable member 60, and the fitting connector 3 remains in contact with the inner connector 40. As shown in FIG. At this time, since the elastic member S2 hypothesized between the movable member 60 and the movable member 50 is elongated in accordance with the movement of the movable member 60, the elastic bearing force of the elastic member S2 gradually decreases. Is increased. And, when the elastic support force of the elastic member (S2) exceeds the insertion load between the fitting connector 3 and the inner connector 40, the fitting connector 3 is in the opening 43 of the inner connector 40 Will be inserted.

When the fitting connector 3 on the side of the cartridge 2 is mounted in the opening 43 of the inner connector 40, the conductive connectors 3a formed in the fitting connector 3 and the inner connector 40 are connected to each other. Each connecting terminal formed in the opening 43 is electrically connected. This makes it possible to reproduce or record digital data between the recording medium 1 and the apparatus main body provided with the recording medium mounting apparatus 10.

As shown in FIG. 9, when the fitting connector 3 and the internal connector 40 have been attached, the control pin 15a of the swinging member 15 is the second sliding groove 12b of the cam member 12. The oscillation member 15 is oscillated in the clockwise rotation direction in FIG. At this time, since the pressurizing portion 15b of the rocking member 15 presses the actuator 17b1 of the second switch member 17b, the controller controls that the cam member 12 has reached the state where the mounting of the connector is completed. I can figure it out.

In the beginning of the loading operation, the sliding pin 93 of the power transmission means 90 is moved in the insertion direction by the circular arc groove 12a1 of the first sliding groove 12a, but as shown in FIG. 8. When the sliding pin 93 passes the connecting portion 12a4 of the first sliding groove 12a, this time, the sliding pin 93 is moved in the insertion direction by the small arc groove 12a2.

Here, since the large arc groove 12a1 is formed with a large curvature compared to the small arc groove 12a2, the sliding pin 93 is shown in FIG. 3 while the cam member 12 is almost half a turn. The movement distance L1 from the position a1 of the wide part 12a3 to the position a2 of the connection part 12a4 shown in FIG. 8 is moved. At this time, as shown in FIG. 8, the movement amount of the locking part 74 of the pulling member 70, ie, the movement distance with respect to the insertion direction of the cartridge 2, is L0.

The relationship between the moving distance L0 of the cartridge 2 and the moving distance L1 of the sliding pin 93 is L0 ≦ 2 · L1. That is, in this recording medium mounting apparatus 10, when the said large arc groove 12a1 is used, the moving distance of the sliding pin 93 (namely, the slide member 80 which mounted the power transmission means 90) ( The movement distance L1 of the cartridge 2 can be moved by about half or less of L1.

On the other hand, from the process of reaching FIG. 8 to FIG. 9, that is, from the position a2 of the connecting portion 12a4 to the position a3 reaching the innermost circumference 12a5, the sliding pin 93 is moved by the said small arc groove 12a2. Since the radius of curvature of the small arc groove 12a2 is small, the moving distance L2 from the position a2 to the position a3 while the cam member 12 is turned about half a turn. Move it. At this time, as shown in FIG. 9, the movement amount of the locking part 74 of the pull-out member 70, ie, the movement distance with respect to the insertion direction of the cartridge 2, is L3. That is, in this recording medium mounting apparatus 10, when the small arc groove 12a2 is used, the moving distance of the sliding pin 93 (that is, the slide member 80 on which the power transmission means 90 is mounted) ( The moving distance L3 of L2) and the cartridge 2 are almost the same (L2_L3).

As described above, the number N1 of the large-diameter pinion gear 91 and the number N2 of the small-diameter pinion gear 92 have a relationship of N1> N2. Therefore, when the small diameter pinion gear 92 rotates the first rack portion 21a by the number of teeth n, for example, the number N1 / of the second rack portion 62 engaged with the large diameter pinion gear 91 is engaged. It becomes possible to move by N2) .n (> n). In other words, the amount of movement in the Y direction of the movable member 60 having the second rack portion 62 and the movable member 50 connected to the movable member 60 via the elastic member S2 is determined by the power transmission means. 90, that is, the amount of movement in the Y direction of the slide member 80 on which the power transmission means 90 is mounted can be increased.

That is, in the recording medium mounting apparatus 10 of the present invention, it is possible to move the cartridge 2 by a long moving distance of twice or more with respect to the moving distance of the slide member 80. Therefore, since the movement distance of the slide member 80 in the Y direction can be reduced, the recording medium mounting apparatus 10 can be miniaturized.

In addition, if the rotational speed of the cam member 12 is made constant, the cartridge 2 is moved while the cam member 12 is first turned halfway (while the sliding pin 93 is moved in the circular arc groove 12a1). Is moved by the travel distance LO and by the travel distance L3 while turning the remaining half wheel (while the sliding pin 93 is moving in the arc arc groove 12a2). That is, most of the movement of the cartridge 2 is performed by the circular arc groove 12a1, and the circular arc groove 12a1 functions as a moving conveying portion for moving the cartridge 2 in the insertion direction.

In addition, since the relationship between the moving distance L0 and the moving distance L3 is L0> L3, it is possible for the large arc groove 12a1 to convey the cartridge 2 at a higher speed than the small arc groove 12a2. . Therefore, when the cartridge 2 is inserted into the inserting portion 10A, the cartridge 2 can be quickly drawn into the recording medium mounting apparatus 10. For this reason, the time required for attracting the recording medium 1 to the inside of the recording medium mounting apparatus 10, even if the recording medium 1 whose outer dimension is long in the Y direction, as in the large (2.5-inch type) hard disk is shortened. can do.

In addition, when the fitting connector 3 of the cartridge 2 is mounted on the internal connector 40 on the recording medium mounting apparatus 10 side, a wish in which the sliding pin 93 is formed on the inner circumferential side of the cam member 12 is provided. Since the arc groove 12a2 has been reached, the sliding pin 93 is driven with a torque larger than that of the large arc groove 12a1 on the outer circumferential side. Therefore, since a large pulling input (tracting force) is generated in the drawing member 70, the fitting connector 3 and the inner connector 40 can be fitted and connected with a stronger force. That is, the small arc groove 12a2 of the cam member 12 functions as a connecting portion for mounting the fitting connector 3 and the internal connector 40 with a stronger force.

In addition, when the sliding pin 93 is moved in the small arc groove 12a2, the elastic support force of the elastic member S2 as described above is inserted between the fitting connector 3 and the internal connector 40. The fitting connector 3 is inserted into the opening 43 of the inner connector 40 in excess of the load.

Therefore, in the recording medium mounting apparatus 10 of the present invention, in addition to the large pulling input by the pulling member 70, the pulling force of the elastic member S2 acts as an auxiliary, so that Since the fitting connector 3 can be completely fitted with respect to the internal connector 40, the fitting connector 3 and the internal connector 40 can be securely mounted.
